The BeepEi Elvis plays three different melodies for three degrees of hardness: VIVA LAS VEGAS - for wimps HOUND DOG - for medium-soft eggs JAILHOUSE ROCK - for hard eggs The return of the king! Even people with previous orthopaedic problems will now swing their hips, because the “King is back”. Well, for some, he never left us, but that's another issue. With the BeepEi Elvis, good old Rock N' Roll gets into the cooking pots. Too soft, too hard — but never to the point. Perfectly cooked eggs are a science in themselves. But no problem for the Beepei Elvis. Simply store with the eggs, cook with the eggs and wait until the clever egg timer sings. No matter what water temperature you start with and no matter at what altitude you cook, the egg will be perfect.
